To all whom it ma concern:

Be it known t at I, EMIL CAESAR RU- noLrH, a subject of the German Emperor, residing at Springville, in the county of Erie and State of New York, have invented certain new and useful Improvements in Boiler Attachments for Locomotive Fire- Boxes; andl do hereby declare the followa series of small copper pipes through the fire-box direct above the fire back to the boiler to generate steam more quickly andto thus save fuel, the copper pipes leading from the one portion of a Water jacket from the front wall at the lower part of the tirebox into the water jacket above the fire-door back to theboiler. These and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which- Figure 1' is a longitudinal sectional. View of ..tl1e fire-box, (except boiler), the boiler attachment and adjacent parts." Fig. .2 is a. front plan view ofone of the hollow cylin dcrs to which the pipes are connected, showing the walls of one of the water jackets in section, and with the side walls of the firebox. Fig. 3 is a. top plan View from the front elevation of the flange attaching members for the hollow cylinder, and Fig. 4 is a similar View of the flange attaching members for the lower cylinder.

Referring to the drawing, the numeral 1 designates a boiler, Bare the lire fines ex: tending longitudinally of the boiler and. at tached to the front wall 3 thereof. The tiregrate in the fire-box may be of the usual construction, and 5 is the fire-door.

The numeral designates a. water jacket which communicates with the boiler and ex- 7 tends over the top of the fire-box, and conand extending nearly across-to the side walls 20 thereof is a hollow cylinder 14 provided with anopening 17 and attaching flange 15 secured by studs 16 to the Wall. 3 of the firebox below the fines 2 and communicating through the opening 17 with the water jacket 8 of the boiler. Secured to the upper Wall 9 of the fire box, and extending nearly across to the side walls '20 thereof is a. similar hollow cylinder 10 provided with an openiuu ll and attaching flanges 12, secured byst'ugle 13 to the wall 9 of the lire-box abov'e the lire-door 5 and communicating through the opening 11 with the water jacket 6 of the. boiler, I 1

Connected to a series of perforations 18in the hollow cylinder 14: and equal perforations in the hollow cylinder 10, are copper pipes 19 of comparatively small diameter,

said pipes are secured by unions 21 to the cylinders l4 and 10 and readily removable 1 when required. for cleaning or for other puroses. v

When the fire is started in the fire-box, the water line will be somewhat above the top of the opening 11 in the cylinder 10 "and when steam begins to generate the Water will circulate from the water jacket 8 through the opening 17 into the cy inder l4 and through the pipes 19 into the 'cylinder 10 as steam, and through the opening 11, into the Water jacket 6 and will keep up a constant circulation. The pipes 19 being located immediately above the bed 0t fire will be quickly heated in the firebox, and will r sult in generating steam much quicker than by the ordinary boiler, in which the heat is utilized only'in passing through the flame tubes or fines 2.

From the foregoing it will be obvious that a boiler attachment made according. with this invention will be u great'saver of fuel and labor, and will generate steam much more quickly than by the ordinary process.

The boiler attachment may be readily connected to any boiler without material. expense and alteration.
